The globe valve operation principle
For example, suppose a Daigai storage tanks, water from entering the Bottom, from Gangkou outflow valve cylinder head on the equivalent of the closed cases. If the head with their hands up against, the equivalent of the Globe valve works. If hand-off to the next to the cylinder head, which is equivalent to the valve works.
The main criteria:
1, design standards: GB / T 12235
2, connected:
1) butt-end BW: according to GB / T 12224
2) flange-end RF: by JB79; GB / T 9113; HG20592
3, valves and pilot testing:
GB / T 13927; JB / T 9092
The following structure:
Class 150~1500 Cast Steel Globe Valve
Class 600~2500 Pressure Sealing Globe Valve
Class150-1500 Forged Steel Globe Valve
Ming-under-stent
Valve cover bolt connections; pressure from the tight-valve cover
Overall on-sealed Block
Details:
The valve is headstock cylindrical pieces of the flap valve, sealing surface flat or cone, the flap valves along the center line for the fluid movement in a straight line. The movement in the form of stem, a leveraged take-off and landing (landing and taking off stem, the hand movements do not round), but also leveraged spin off and landing (handwheel stem together with the rotation movements in the nut on the valve body). globe valve is only applicable to full-and customs-wide, custom-made to allow time for conditioning and reducing expenditure. Open the valve, the valve open the valve height, for the nominal diameter of 25% to 30%, the flow has reached the maximum, that valve has reached wide-open position. Therefore, the cut-off valve wide-open position, travel flap valve should be determined.
